4.5 and 5.5 would be twice the HP you'd ever use in offroad... in onroad sedan traction is always available, so they can run mega HP. Even 2.5s

If you want to run mod car, I would suggest a 7.5-8.5 all the way down to a 10.5. geared right, there is very little difference in lap times.

Even consider a 13.5, a couple week ago I ran stock for the hell of it and ran within 6 seconds of mod TQ It'll all about being smooth and corner speed... straight line speed means nothing.

The most you will ever need in a 2wd buggy is a 6.5 if you want to have an really over powered car (mostly used in trucks), then in the 2wd buggies a 7.5 would be your best best for the highest powered motor you would want to use. Although if you had a 4wd buggy then you can get away with the 5.5. Although really an 8.5 is a lot of motor.

Ok, good to know and thanks for the recommendations on motors sizes, your reasons make perfect sense.

But I still have the question: Are there onroad and offroad specific brushless motors? Or can I pretty much buy any BL motor I want and slap it in a B4 and expect it to perform the same way any other BL motor would for offroad purposes?

If you run on low traction, larger tracks the "L" series motors can be good. They are like the triple wind version of BL motors. They do sacrafice total power, the 7.5L makes the same wattage as the 10.5 standard version. The 7.5 would have much more revability.

You will also find that BL motors, especailly the milder ones (8.5 through 17.5) like to be geared tall. They actually gain bottom end with taller gearing because they react well to the load. Be careful no to go too far, you will want to watch motor temps.

I run a 10.5 geared 25/81 and that's actually pretty low for that motor.

I run @ 53.5 oz with about the same setup as the AE guys use with heavy stuff. My car is really fast. The biggest thing is not to over-motor it.

Here's a link, post it up.

Edit, I think I have the weight wrong, I believe I'm @ 55.5oz.
